MUNICIPALWASTEWATER TREATMENT

When water is contaminated after been used and that it can not more been used by other users or exceeds the natural assimilative capacity of the receiving stream, it is termed "wastewater".

When the major source of pollution is not industrial, most wastewater is termed "municipal".

It includes,

  • important communities: hamlets, towns, cities.

  • small communities or sites of activities: hotels, restaurants, camping's, entertainment parks, isolated houses,

Municipal wastewater treatment is principally based on biological methods. Various micro-organisms living in natural waters can feed on an amazing variety of dissolved and suspended organic compounds. When there living conditions are not more meet, there action are slowed down. A biological wastewater treatment plant create the best living conditions for these micro-organisms to optimise the elimination of many pollutants.

The determination of the effects of water discharge on the natural assimilative capacity of the local receiving site, leads to the definition of the degree of treatment necessary to protect nature.

The amounts of pollutants which may be discharged are defined in the discharge permit, issued by the local authorities

Working for a local authority, or being as private confronted with a wastewater discharge, you may describe us your problem. We always have a solution.

The size of our wastewater treatment plants extends from several hundreds to several tens of thousands of inhabitants. When needed, special purification methods so as nitrification & denitrification, dephosphatation

If in your scope of needed services, you wish to include buying, installing and starting-up of the equipment (with or without preliminary studies), HYDRO-TECHNOLOGY s.a. will be your partner. As "general contractor" we will then design and drawn your complete plant, and locally work with subcontractors for the erection of buildings and basins, for the mounting of mechanical and electrical equipment. Start-up will be done by our own engineers.

If you wish only conception and study of the plant by a specialist in water treatment, HYDRO-ENGINEERING s.a. will be your partner. We will then design and drawn the complete plant, describe all needed mechanical and electrical equipment, so that you can work with subcontractors for the erection of buildings and basins, for the mounting of mechanical and electrical equipment. Start-up can be supervised by our engineers.

DRINKING WATER

The most important sources of fresh water in Europe are surface water and ground water. The portion of rain and melting snow collected in ponds, lakes, creeks and rivers is termed " surface water ". The portion of rain and snow soaked into the ground is termed " ground water ".

These waters carry many impurities : solubilized minerals, particles, organic material (dissolved or in suspension), dissolved gazes. Many of those impurities are not compatible with the use of those waters for drinking purposes. The variables of impurities are influenced by the source from which the water is taken. The means of treatment must be chosen case by case.

If your purpose is the making of drinking water from surface water or from ground water, in closed vessels for small quantities or in open basins for large quantities, we are able to propose the treatment adapted to your water.

Our plants meet many requirements: from supplying drinking water to big cities by complete purification plants, to supplying small hamlets, isolated building sites and communities, sites accidentally deprived of water.
